∞ Apple releases MainStage 2.1.1

Apple on Wednesday released an update for its professional guitar and keyboard app, MainStage. According to notes accompanying the update, MainStage 2.1.1 improves stability of the 32-Bit Audio Unit Bridge and fixes a problem that caused audible artifacts when using the Playback or Loopback plug-ins.

The Audio Unit Bridge is a feature that was introduced as part of the Logic Pro 9.1, MainStage 2.1 update in January. In addition to adding 64-bit support to the apps, Apple gave users a way to continue using their 32-bit plug-ins — Audio Unit Bridge.

The only restriction in using plug-ins with the bridge is that the plug-ins themselves are still guided by 32-bit restrictions.

MainStage 2.1.1 is available via the software update mechanism in Mac OS X.
